Question

Trees on mountains have conical shape give reason

Answer 1

The conical shape helps to shed the snow easily and quickly. The needle like leaves does not allow accumulation of snow at a concentrated place, leading to increase in load.

They have conical shape due to evolving to adapt to the above-mentioned conditions.

Answer 2

So it stands to reason that longer branches are lower down and the branches are successively shorter as you move up to the tree's apex. This is what gives rise to the conical shape. ... At high altitudes, conifers (cone-bearing trees) such as pine and spruce dominate over broad-leafed deciduoustrees such as oak and maple
